I love the idea of turbo-ing my k-jet. There's an Australian blog with a guy that's done it to a mk1 golf so very similar, uses saab, volvo and Audi parts along with obviously some custom bits. Very inspiring read but way above my abilities... And finances. I might just have to settle for some head work and cam. My first mk2 was a gti engineering one. I'd love to replicate the work but keep getting told pound per power gain isn't worth it, everyone just wants to bung in modern power plants, but I don't care for that, just love the characteristics of a tuned k-jet I ported and polished my own head on my 8V, its not that hard, a bit time consuming maybe. A die grinder and compressor, a carbide burr, good quality emery cloth, etc

Yeah, one day. I fancy giving it a go, but on a spare head first. I keep my eye out if I find one local and keep I'll probably have it and stash it in the garage for a rainy day.

Drat, drat and double drat!
Think I'm back to square one. After a few months of trouble free since replacing the WUR I'm getting the same symptoms occurring that I started this thread with in the first post, unhappy when cold, lumpy when running and down on MPG.
This raises the question is it possible to damage a WUR? and could I have some problem that's caused a second one to fail?
The other thing of interest is may car has always run quite cool, but it's hard to tell as the majority of my daily route is a quick fling up the motorway, so I just thought I had an effective radiator. But it's been suggested the thermostat could be stuck, sticking or partially operating. I've got a new one on order, but as the system relies on thermo switches that change the fueling based on temp.... Could this potentially be playing a part of my issues?

Bit of an update, Finally the missing fuel line from the HEL kit arrived. So this, became this Shame it didn't come with a new stainless banjo bolt :sad: And this, became this, and all was right with the world once more. I also popped the boot on the metering head, and was greated with an oily mess again So I blasted it with carb cleaner, I forgot to take the after photo but it was spotless after. I also did the other end and blasted some carb cleaner through the throttle body. So, why is this happening? Well this might have something to do with it, Mayo build up in the breather again! Again quickly whipped off the pipe and flushed it through, carb cleaner is expensive per can but it's fantastic stuff! Fired up, left it run for a while, then I was able to wind back in the idle screw, which I'd had to wind out to try and compensate for the poor running I was getting. I thought perhaps I'd killed another WUR, but I think now it's just a build up of oil in the intake. So what causes excessive oil in the breather? am I be looking at getting the valve stem seals replaced?

Blocked PCV valve would cause this.They should be changed every few Services.

Ok, going to make myself look stupid(er) now, what's the PCV valve and where will I find it?

Positive crankcase ventilation
Either a breather assembly bolted to the or around the engine block , or sometimes incorporated into the filer cap

Ah, the ufo type thing. Early golf didn't have that, came in with the later digi engines. Mine does have a gauze inside the cover. I know these are prone to clogg and hard to clean so I've managed to locate a genuine new cover, on order direct from Germany so hopefully will sort it when fitted.

Sorry eddypeck my mistake it's a round flying saucer shape breather they tend go on a regular basis. Also check IIRC under this is a rubber bung and all rubber parts on the intake system worth checking on the intake side.

Funny you should ask, I got the car back this week almost 6 months to the day after it's final breakdown. All of the key parts got sent away to KMI for investigation and it was reported back that the whole lot was scrap due to contamination. The contamination goes back to the October 2013 when the car has some welding done. A repair patch to the rear inner wing, when cutting the patch they nicked the filler neck.... and left a hole. I ran the car like this all winter, every time it was damp the car would struggle. I didn't discover the damage to the tank till the following spring when after a FULL tank I discovered a puddle of fuel on the floor. I would usually fill up on my way to work, so even if I'd filled right to the top of the neck the level would be below the cut by the time I parked. On this one occasion I filled up at the end of the day so parked with a full tank. I did a plastic repair to the filler neck, but still suffered unreliable driving for almost the next year. The water and dirt that got into the system during this time had continued to plague the car and destroy the fine tolerances of the internal workings of the mechanical injection until it would go no more. As it stands now, the fuel tank has been replaced, the fuel lines have been replaced where required or blown through, the internal pump has been replaced (again) and the under car pump has been replaced with an uprated Ford item. The filter has obviously been replaced. The metering head and fuel distributor has been reconditioned and the WUR has been reconditioned (I had the opportunity of a 16v one so that was used - allowing better control as it's adjustable) all 4 injectors were replaced. The car has been set up on the rolling road, returning 120bhp. Which I'm pretty pleased with as it was 112 out of the factory 29 years ago. It's a joy to drive now so looking forward to many years of trouble free motoring.

Soaking it in a bucket of petrol usually does the trick. its the same as on the carb engines iirc. I did cheat on mine though, and just fitted an oil catch can in the pipe from the rocker cover breather

Glad you've got it sorted
